Description

Es sind bereits Leichtmetallbalken für die Herstellung der Fahrbahn von Pontonbrücken bekannt. Diese Balken haben einen rechteckigen Querschnitt, sind hohl und weisen auf der unteren Seite angeschweißte oder angeschraubte Lappen auf, mit denen sie auf der Unterlage, z. B. auf den Querträgern, welche auf die Pontons gelegt werden, mittels Bolzen befestigt werden. Diese vorstehenden JLappen sind beim Verladen der Balken und beimThere are already light metal beams known for the production of the roadway of pontoon bridges. These beams have a rectangular cross-section, are hollow and have welded-ons on the lower side or screwed-on cloths with which they can be placed on the surface, e.g. B. on the cross members, which are placed on the pontoons are fastened with bolts. These above Jcloths are used when loading the beams and when

ίο Transport sehr lästig. Dieser Nachteil wird durch den Leichtmetallbalken gemäß vorliegender Erfindung vermieden.ίο Transport very annoying. This disadvantage is caused by avoided the light metal beam according to the present invention.

Der erfindungsgemäße Leichtmetallbalken, der ebenfalls hohl ist und einen mindestens annähernd rechteckigen Querschnitt aufweist, zeichnet sich aus durch eine längs laufende Ausnehmung an der unteren Seite, die auf die Unterlage zu liegen kommt, und durch in der Ausnehmung gelenkig angebrachte, zurückklappbare Befestigungslappen.The light metal beam according to the invention, which is also hollow and at least approximately one Has a rectangular cross-section, is characterized by a longitudinal recess on the lower side, which comes to lie on the base, and by articulated in the recess, retractable fastening tabs.

Beim Transport wird der erfindungsgemäße Leichtmetallbalken umgekehrt, so daß die Ausnehmung nach oben zu liegen kommt. Die gelenkig angebrachten Lappen klappen dann von selbst in die Ausnehmung zurück und stehen dann nicht mehr vor.During transport, the light metal bar according to the invention is reversed so that the recess comes to lie on top. The hinged flaps then fold in by themselves the recess back and then no longer protrude.

Der erfindungsgemäße Balken ist gegebenenfalls, wie die bekannten Leichtmetallbalken, an beiden Enden wasserdicht geschlossen, so daß er im Wasser schwimmt.The beam according to the invention is optionally, like the known light metal beams, on both Ends closed watertight so that it floats in the water.

Im Gegensatz zu den bekannten Leichtmetall-. balken mit starr angebrachten Befestigungslappen, für deren Verbindung auf der Unterlage Bolzen verwendet werden, wird der erfindungsgemäße Leichtmetallbalken an den gelenkig angebrachtenIn contrast to the well-known light metal. beams with rigidly attached fastening tabs, bolts are used for their connection on the base, the inventive Light metal bars attached to the articulated

35" Befestigungslappen mit Hilfe von Keilen auf der Unterlage befestigt, was das Zusammenpassen sehr vereinfacht und eine beschleunigte Montage ermöglicht. 35 "fastening tabs attached to the base with the help of wedges, which makes them fit together very well simplified and enables accelerated assembly.

Die Handhabung des Balkens wird gemäß einer weiteren Ausbildung der Erfindung dadurch weiter erleichtert, daß er an beiden Enden mit drei Längsöffnungen versehen ist, wovon eine im oberen Teil und die beiden anderen beidseitig in den Seitenwänden angebracht sind und eine bequeme Einführung von zwei Händen hintereinander gestatten. Zwischen der oberen Längsöffnung und den zwei seitlichen ist der Balken innen mit zwei Handgriffen versehen. Selbstverständlich müssen die Abschlußwände des Innenraums des Balkens (wenn solche vorhanden sind), von den Enden desselben aus gesehen, hinter den öffnungen angebracht sein.The handling of the beam is thereby further developed according to a further embodiment of the invention facilitated that it is provided with three longitudinal openings at both ends, one of which in the upper part and the other two are attached on both sides in the side walls and are easy to insert allow two hands in a row. Between the upper longitudinal opening and the two the side of the bar is provided with two handles on the inside. Of course they have to End walls of the interior of the beam (if any) from the ends of the same from behind the openings.

Die öffnungen an beiden Enden des Balkens gestatten dessen bequemen Transport durch vier Mann. Bei den bekannten Leichtmetallbalken für Pontonbrücken sind an den Enden Quergriffe angebracht, wodurch das Tragen weniger bequem ist, · da die Hand um 9ο'01 gegerf die Normallage gedreht gehalten werden muß.The openings at both ends of the beam allow it to be easily transported by four men. In the known light metal bars for pontoon bridges cross handles the normal position at the ends attached, so wearing is less convenient because · hand to 9ο '01 gegerf must be kept rotated.

Der erfindungsgemäße Leichtmetallbalken wL-d vorzugsweise aus einer hochfesten und korrosion^- beständigen Aluminiumlegierung hergestellt.The light metal beam according to the invention wL-d preferably made of a high-strength and corrosion-resistant aluminum alloy.
